Calluna Pharma

Calluna Pharma is an Oslo-based clinical-stage biotech building first-in-class antibodies that switch off the upstream signals driving inflammation and fibrosis. Formed in 2024 from the merger of Oxitope Pharma and Arxx Therapeutics and backed by a EUR 75 million Series A, the company targets damage-associated molecular patterns (DAMPs) such as S100A4 to halt diseases like idiopathic pulmonary fibrosis at their root rather than managing symptoms.
